Definitions

  • the invention relates to a method and a device for preparing liquids for fertilizing plants for household or hobby gardeners.
  • Watering systems and fertilizer systems for household and hobby gardeners are also known, with which plants or beds can be watered over a long period of time and to the required extent, or the required fertilizers can be added to the plants using fertilizer sticks or liquid fertilizers.
  • this object is achieved by the steps of claim 1 or by the measures of claim 2.
  • the irrigation water can also be enriched with C0 2 and H 2 C0 3 only if necessary.
  • the watering liquid provided in this way promotes the growth, flowering, yield and resistance of the plants to pests or infestation to an unusual degree.
  • the water pressure in the supply line can vary widely, for example between 1 bar and 7 bar.
  • the direct pressure control of the withdrawn water for the outlet and reducing valve of the gas pressure container ensures precise and simple automatic control of the feed pressure of the C0 2 gas to the contact zone with the water in any case. In this way you get a fully automatic and accurate and reliable control of the feed pressure for the C0 2 gas. At the same time you get an extraordinarily high one Ease of use.
  • the respective pressure of the water taken from the supply line can also be used as the delivery pressure, indirectly by acting on the feed pressure of the CO 2 gas, which is controlled by the water pressure, on the head space or on the outside of a flexible container for the liquid fertilizer leaves.
  • the pressure-dependent feeding of the fertilizer into the contact zone can, however, also take place by negative pressure, as it arises in the individual injector nozzles of the contact zone, and also depending on the pressure of the water in the supply line.
  • a device block 1 which has a connection 2 for connection to a conventional water supply line.
  • a ver supply line connection point is usually equipped with a shut-off valve.
  • a control chamber 3 is provided, into which the water enters from the line.
  • the inlet pressure of the water can vary within wide limits depending on the respective supply line, for example between 1 bar and 7 bar. Likewise, the respective temperature of the water removed can be very different.
  • the respective pressure of the water in the control chamber 3 acts on a membrane 4, which acts via an actuating plunger 8 directly on the movable member 7 of the outlet and reducing valve of a C0 2 pressure vessel 6, for example a conventional compressed gas bottle.
  • the pressure vessel 6 equipped with this valve only needs to be screwed in a sealing manner to the standardized connection of the device block 1 provided for this purpose. Such a valve closes automatically if no control pressure is applied to the valve member 7 from the outside.
  • a gas distribution chamber 5 is provided in the device block 1, which is connected to a gas chamber 10 via a throttle point 11.
  • a flow channel 13 is also provided in the device block 1, the inlet side 14 of which is in free flow communication with the control chamber 3.
  • the flow channel 13 is preferably straight and elongated and opens out at its lower end at an outlet 28. This can be the direct outlet for the pouring liquid, for example for filling watering cans or other containers. However, a conventional garden hose or the like can also be connected to the outlet 28.
  • the flow channel 13 has a plurality of channel sections, the diameter of which progressively and abruptly increases. These injector nozzle-like sections are designated 15a to 15c.
  • the flow channel each has a plurality of connection openings 17, which are in free flow connection with distributor channels 12, which in turn are connected to the gas chamber 10.
  • a feed pipe 25 projects centrally from above and at a radial distance from the wall of the flow channel, said feed pipe 25 having a shut-off valve or metering valve 26 Fertilizer supply for liquid fertilizer is connected and opens in the area of one of the injector nozzles 15a to 16b.
  • the mouth 27 lies in the area of the injector nozzle 15c.
  • the negative pressure in the flow channel in one or the other of the injector stages 33 can also be used to suck the fertilizer from a reservoir 38 via the suction line 36 and the riser line 39, depending on the pressure, while at the same time sucking in the gas via the gas chamber 32, 34.
  • a separate injector stage can also be provided between the injector groups 33 and 35, which serves exclusively to suck in the fertilizer. 2 can also be used in connection with the pressurization of the fertilizer supply by the C0 2 gas pressure in the gas chamber 32, 34.
  • a device block 30 is again provided which combines all the essential parts and connections of the device and thus enables particularly simple control.
  • a water-soluble solid fertilizer can also be used instead of a liquid fertilizer.
  • the device block is designed such that the water flow through the flow channel 13 according to FIG. 1 rinses the solid fertilizer and releases an amount of fertilizer corresponding to the amount of water.
  • the valve 7 is practically a simple shut-off valve which is held in its locked position by the internal pressure in the container 6.
  • the internal pressure is e.g. 60 bar and can fluctuate depending on the temperature.
  • the area ratio of the sealing area of valve 7 and membrane area is, for example, about 1:60.
  • the container is shut off at atmospheric pressure in the device. Now it works Water pressure on the diaphragm translates the pressure effect that it transmits to the valve by a factor of 6.
  • the valve opens, gas (CO 2 ) flows into chamber 5, from which the outflow is throttled, as already described.
  • the membrane 4 translates all fluctuations in the water pressure and thus controls the C0 2 outlet as a function of the water pressure and its fluctuations.
  • gas bubbles of oversized size will still be present when it exits the impregnation system.
  • These gas bubbles must be filtered out in such a way that they are supplied to the gas impregnation room itself so that they are not transported to the delivery point. This would mean that larger bubbles would escape into the atmosphere and thus the economy with regard to the use of gas would be impaired.
  • This process can be prevented by installing a helix, but better by installing a meandering system that runs vertically in the system, with the highest point opening into the gas space. At this point, one or more outlet openings can be made that allow the lighter gas to escape at this upper point so that it can be fed back into the gas space of the injector system while the filtered and finely impregnated water is conveyed into the discharge zone.
